Well, since you are a reader you might enjoy a trip to the book store or library. There are TONS of books devoted to the smoothie... how to make them, what benefits they have, ect. We have a few here but, sadly, our blender went to be with Jesus and we don't have extra funds for a new one yet so no smoothies for me right now
. Insert jealous-self-pity sigh here.
My sil makes one her family loves and its packed with spinach and all kinds of good for you stuff in it but it actually tastes good.
